Role of "Intrinsic Charm" in Semi-Leptonic B-Meson Decays
C. Breidenbach, T. Feldmann, T. Mannel +1
We discuss the role of so-called "intrinsic-charm" operators in semi-leptonic B-meson decays, which appear first at order 1/m_b^3 in the heavy quark expansion. We show by explicit…

SCET sum rules for B->P and B->V transition form factors
F. De Fazio, Th. Feldmann, T. Hurth
We investigate sum rules for heavy-to-light transition form factors at large recoil derived from correlation functions with interpolating currents for light pseudoscalar or vector…
